Referring now to FIG. 1, the roof of the vehicle is designated by the numeral 10. Mounted on the roof 10 is a vehicle top carrier 11 which includes two identical corner support assemblies 12 forming one pair of corner support assemblies and a second pair of corner support assemblies 16. Each corner support assembly 12 includes one collar 20, while each corner support assembly 16 includes two collars designated by the numerals 20 and 20'. Support assemblies 12 are mounted on the vehicle roof 10 with the collars 20 facing the collars 20 on the support assemblies 16. With such a construction, the collars 20' face one another. Tubular rail elements 24, 26 and 28 are provided between the adjacent rail support assemblies 12 and 16 as best illustrated in FIG. 1.

The vehicle top carrier 30 illustrated in FIG. 3 is I similar in construction to the vehicle top carrier 11 illustrated in FIG. 1 with the exception that the rail support assemblies 12 are each provided with two collars 20 and 20' rather than one collar as in support assembly 12. With such a construction an additional rail 32 is provided between the adjacent rail support assemblies 12 and 14' as best illustrated in FIG. 3; otherwise the vehicle top carrier 30 is identical to vehicle top carrier 1 1.

The rail support assembly 12, 12' and 16 is best illustrated in FIG. 6 and comprises an upstanding post 34 made from a suitable metal or alloy thereof having a hollow interior 36 and including a top wall 38 and generally inclined or downwardly tapering side walls 40 to provide an ornamental and attractive appearance. The top wall 38 is provided with an opening 42.

A closure element or rail fitting 44 is provided having a nose or cone shape portion 46 and a generally hollow interior 48. The closure element 44 may be made from a suitable metal or from a suitable metal alloy. The closure element 44 further includes a downwardly extending stem 50 which is provided with a centrally located cavity and an opening 62, said stem 50 being adapted to be received in the opening 42 in the top wall of the post. The bottom surface 52 of the stem 50 coincides with the inner surface 54 of the top wall 38. The upper wall 56 of the closure element 44 is provided with an opening 58 which is in communication with the hollow interior 48 and the cavity 60 and opening 62 provided in the stem 50 as best illustrated in FIG. 6. A resilient spacer or washer 64 is interposed between the bottom of the closure element 44 and the top wall 38 of the post 34 and surrounds a portion of the stem 50.

Each corner or rail support assembly 12, 12' and 16 is provided with one or more openings 66, each opening defining a collar 20, 20' for receiving one end of a rail as described previously.

A resilient generally elongated adapter base 70 is interposed between the bottom surface 72 of the post 34 and the roof of the vehicle, with the resilient adapter base 70 being adapted to conform to the shape of the vehicle roof 10. The adapter base 70 is provided with longitudinally spaced recesses 72 and 74 in the bottom surface 76 on opposite sides of an opening 78 which extends between the top surface 80 and bottom surface 76. The opening 78 is aligned with the openings 62 and 58 provided in the closure element 44 and is in communication with the interior of post 34. The annular portion 82 of the adapter base 70 surrounding the opening 78 forms a resilient bushing 82 for a nut or rivet 84. The outer peripheral rim portion 86 of the base 70 forms a sealing element which engages the roof 10.

The nut or rivet 84 is a conventional one-piece blind rivet or fastener provided with internal threads 85 and is sold by The B. F. Goodrich Company under the Trademark Rivnuts. The rivet 84 is originally of cylindrical configuration having an annular flange 86 on the upper end thereof. In assembly, the nut 84 is inserted into the opening 78 provided in the adapter base 70 and extends through opening 88 provided in roof 10, with the flange 86 resting on top surface 80 of the adapter base 70.

Thereafter an elongated standard socket head cap screw 89, threaded on one end, is inserted through the opening 58, cavity 60 and opening 62 in the closure element 44 and then through the interior of the post 34 and is finally brought into threaded engagement with the nut 84. As a result of the threading action between cap screw 89 and nut 84 and intermediate U-shaped portion 90 of nut 84 is urged laterally outwardly to engage the inner surface of roof 10 as shown in FIG. 6 to fixedly secure nut 84 between the adapter base 70 and roof 10.

Once the head 92 on cap screw 89 abuts shoulder 94 on stem 50 the fastening means is secured with the closure element 44, post 34 and adapter base 70 held firmly together on'roof 10. Thereafter a plastic plug 96 having a rim portion 98 is inserted into the opening 58 in closure element 44 to close same. The annular lip 100 provided on plug 96 engages the top surface of wall 56 and forms a fluid tight seal around opening 58.

FIG. 5 illustrates a further modification of the present invention. In some applications it may be desirable to provide additional styling for appearance purposes. In such case an elongated trim bar 106 is utilized. The washer or spacer 64 illustrated in FIG. 6 is not utilized when trim bar I06 is utilized. The trim bar 106 has an opening, not shown, on one end 108 through .which the stem 50 of closure element 44 extends. End 108 of trim bar 106 may be provided with an integral bushing or washer, not shown, somewhat like washer 64.

Trim bar 106 extends forwardly away from the rail support assembly in alignment with tubular rail 28. As the trim bar 106 extends forwardly it also slopes or tapers in a generally arcuate path toward the roof of the vehicle as best illustrated in FIG. 5. The forward end of trim bar 106 is provided with a reversely turned flange 110 which engages the roof of the vehicle in general friction contact therewith. However, separate fastening means may be provided if required to connect trim flange 110 to the roof of the vehicle. It should be appreciated that any number of decorative trim bars 106 or like elements may be employed with a vehicle top carrier of the present invention.

The rails 24, 26, 28 and 32 are made from metal and are of standard tubular welded construction. The rails have an CD. of inch. The ends of the rails are press fitted into the adjacent collars of the rail assemblies.
